. AXLE FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 265,196, dated September 26, 1882.

Application filed June 14, 1882. (No model.)

To all whom it may concern:

Be it known that I, JASPER P. WARNER, of the city ofDowagiac, county of Cass, and State of Michigan, have invented a certain improvement in adjustable axle-couplings for the purpose of extending or shortening axles, thus placing the driving-Wheels close together or apart, for the purposes hereinafter described in the following specification.

In order to aid others skilled in the art to which myinventiou belongs to make and use it, I will proceed to describe its construction and operations with reference .to the several drawings forming a part of this specification, in which- 'Figure 1 is a side elevation of the axle-couplings, showing also by dotted lines, Fig. 2, the inner axle as drawn or extended. Fig. 2 is a longitudinal sectional view of Fig. 1 on line I 1 of Fig.4. Fig. 3 is a central view of the axle having the-ends broken off and the outer part, B, at the center cut away to show the manner in which the extending partsD are placed when the axle is narrowed or shortened. Fig. 4 is a cross-sectional or end view, showing the pipe B and axle Dcut oft, also giving a side view of the yoke O with pintlea passing through a round hole, a, in the pipe B and resting upon the inner or extending part, D, showing also the clip S passing around the pipe B and up through the yoke U, being held in position by the nuts c c.

The object of this invention is to devise a simple, cheap, and durable coupling adjusta ble axle designed for agricultural machines of that class that may be widened out sufficiently to carrya large number of pulverizers, known as barrow-teeth or cultivator-points, as

inharrowing the soil a wide machine is very desirable, and being able to narrow the ma chine, placing the driving-wheels sufliciently near each other to form a cultivator on wheels and adjustments. The outer central part, B,

I drive-wheels turn.

is hollow. I use for this heavy gas-pipe. Into each end of the pipe is inserted a round iron axle, D, and upon the extreme ends D the Near each end of the tube B a small hole, a, is drilled, as shown in Figs. 2 and 4. These holes are about five-eighths of an inch across and are through one side only of the pipe. Fitting over the pipe I employ a yoke, O. This yoke is arching in the center, and is provided with a hole at each end; and passing around the pipe B and up through the yoke G is a clip, S, being secured to the'yoke by two nuts, 6 e. Theyoke is made of malleable iron, and is provided at the center with a round projection or pintle, a, which passes through the hole a of the tube B. (See Fig.

4.) The end of the piutle (1- forms a bearing upon the inner axle, D, so that when the nuts c e are tightened the pintle a is forced against the inner axle, thus binding it rigidly to the hollow or outer part, B, making a solid coupling. Thepintle ais somewhat longer than the thickness through the part B, in order that it may press rigidly upon the inner part, D, leaving the under surface of the yoke U slightly above the tube B, as clearly shown in Fig. 4. The pintle a, passing through the hole a, prevents the yoke G and clip from sliding out of 'plaeeon the pipe B. To extend the axle or widen the machine, I loosen thenuts ee, when the pressure upon the inner axle, D, is released. Then drawing out the axle D and tighteningthenuts, themachine will be widened in the manner shown .by dotted lines 2 2 of Fig. l, and reversing the above movements JASPER P. WARNER.
